: I have a leak under my kitchen sink. Can't seem to find where it is coming from. Every couple of days or so, there will be a puddle of water under the sink. I have turned on both hot and cold supplies and watched under the sink, but nothing happens. I have filled both sides of sink and drained simutaneously and nothing happens. Any suggestions. THANKS.

What kind of kitchen tap do you have? I've seen single lever taps leak only when putting to much pressure on the handle, this leaks back into the body and out underneath. I've seen leaks caused by water splashing and leaking past the base of the tap as well
